Lanthanum decahydride is a polyhydride or superhydride compound of lanthanum and hydrogen (LaH10) that has shown evidence of being a high-temperature superconductor. It was the first metal superhydride to be theoretically predicted,[2][3] synthesized,[4] and experimentally confirmed[5] to superconduct at near room-temperatures. It has a superconducting transition temperature TC around 250 K (−23 °C; −10 °F) at a pressure of 150 gigapascals (22×106 psi), and its synthesis required pressures above approximately 160 gigapascals (23×106 psi).[6][7]
